Operating the machine

• Pull the rotor (H) approx. 10 mm out of the grinding area until it can be freely
rotated.

Fig. 3: Checking the cutting gap
• Using a feeler gauge (BL), check the cutting gap of all three cutting bars
(SL). It should be at least 0.3mm.
The feeler gauge (BL) must be placed on both cut areas as shown in the diagram.
The cutting gap must show a uniform distance across its entire depth. For this
reason check the cutting gap across its entire depth.
The cutting edge that has the smallest distance to the knife denotes the cutting gap
(SP1/2). The second cutting edge can have a larger cutting gap width.
